Patented Jan. 14, 1930 UNITED STATES PATENT OFFICE ASHTON HEY, OF WAKEFIELD, RHODE ISLAND MEANS FOR ADJUSTABLY ATTACHING WORSTED COMB BRUSHES TO DABBER FEET Application filed February 13,1929; Serial No. 339,681.

This invention relates to a worsted comb brush, the wooden back of which is adjustably secured by bolts (usually two) to a rapidly reciprocating dabber foot. Each bolt extends through a slot in the brush back and is engaged with the dabber foot to clamp the back against the foot, the usual adjustments of the back relative to the foot being permitted by the'slots in the back.

The invention is embodied in a reinforcing lock washer, one for each bolt, insertible in a socket in the back and adapted to lock the back in any position to which it may be adjusted, to prevent the bolts from turning and splitting and warping the back, and to accomplish other useful results, all as hereinafter described.

Of the accompanying drawings forming a part of this specification,-

Figure 1 is a view of the front side of a brush back having reinforcing washers embodying the invention, the brush being removed.

Figure 2 is a view of the rear side of the back showing the dabber foot.

Figure 3 is an edge view of the back and foot.

Figure 4 is a fragmentary perspective view, showing a portion of the back and a socket 0 formed therein for the reception of the reinforcing washer.

. Figure 4 shows a modification of Figure 4.

Figure 5 is a perspective view, showing the washer removed from the back.

Figure 6 is a fragmentary section on line 66 of Figure 2, a portion of the brush being shown by dotted lines.

Figure 7 is a view similar to a portion of Figure 1, showing a difierent adjustment of the locking jaws hereinafter described.

The same reference characters indicate the same parts in all of the figures.

12 designates a comb brush back of the general form used in several types of worsted combing machines, the back being of hard wood and oblong, as shown by Figures 1 and 2.

14 designates conventionally the metal foot of a dabber which is rapidly reciprocated by well known means, to reciprocate the back and the brush 15 attached thereto as usual, the back and brush being reciprocated sidewise. The brushis shown only by Figure 6, by dotted lines. The back is attached to the dabber foot by bolts 16, having heads 17 and clamping nuts 18, engaging threaded portions of the bolts and set up against the foot 14, the boltspassing through slots 19 in the foot. The bolt heads 17 are usually square, 00 and heretofore have been fitted in sockets formed for their reception in the outer side of the back. The wooden walls of said sockets are often cracked and the back warped by the turning of the bolt heads there- My invention obviates this and other objections to direct contact of the bolt-heads with the wooden back, and is carried out as next described. For each bolt 16 I provide a reinforcing lock washer inserted in a socket 20' (Figure 4) formed for its reception in the front side of the back 12. The body 21 of the washer is formed to closely. fit the socket 20, theform of the socket and body being such that the washer body. cannot turn in the socket. In the body 21 isformed a recess 22, in the bottom of which is across-shaped slot 23, form ing two intersecting bolt-receiving ways at right angles to each other. The form and arrangement-of said ways is such that either a crosswise or a lengthwise adjustment of the back 12 on thebolt16is permitted.

- 24, 24 designate locking-jaws pivoted at 25 to the bottom of the recess 22, and adjustable to the different positions shown by Figures land 7 by swinging the jaws on their pivots. The jaws have longitudinal faces adapted to extend parallel with either of the ways formed by the cross-shaped slot 23, and to bear on opposite sides of the bolt head 17,

to lock the bolt against turning in the head, the jaws being backed by wall portions of the recesses, so that they are confined against the bolthead.

The washer recess 22 is provided with angular wall portions 30, having locking faces constituting extensions of the locking faces of the jaws 24, when said jaws are in either of the 1 locking positions shown. The function of constituting extensions of the locking faces said extensions is illustrated by Figure 7 of the jaws. which shows the back adjusted to locate apor- In testimony whereof I have afiixed my tion of one of the extensions in position to signature. bear on one of the sides of the bolt head 17. ASHTON HEY.

The washer and its jaws may be made of' any suitable metal. I v

The chief advantages of'the described improvement areas follows: 1st. The bolt head is locked underalTpossible adjustments ofthe brush back-.-

2nd. The back is reinforced and maintained out of contact with' the bolt head, so that it cannot be cracked orsplit andwarped. lbyl strain tending to turn it relative to the 3rd; Thebrush backis held fastto thedab her foot and cannot be pulled ofi from the bolt. It is well known that if a brush be- 26 comeslooseor comes-off, it'is liable to dam-age the comb circles of aworsteolcombing machine-L; V I

4th. Thelocking'of the bolthead permits a considerable saving of time in changing 25 brushes, and preventsany-neces'sity ofsawing oft the bolt, an operation which might be necessary ifthe bolt werenotpositivelylocked againstv turning.-

5th. The washer may be fitted to various an makes-or forms oi? comb-brush. v t

The back 12 may be provided in the bottom of the s'ock'etQOWitha slot or openingj-ot any 7 form, permitting the: describedustments of the backrelative to the-bolt 16; Asshown by as Figure 4 the bottom of the socket is provided V with-across-shaped slot 27, the same coinciding with the cross-shaped slot23 in the washer. It desired, however; the bottom of the socket may have a straightslota28', as shown by Fig-ure l, andsaid slot mayextendeither m crosswise of the back, t'oxpermit crosswise ad== justment; or'lengthwi'se of the back; to per mitlengthwise adjustment; The slot 28,: in either case is adapted tocoopertmte withthe t m lock washer. v r
